Copper Paste Filled Via PCB

Copper Paste Filled Via PCB

Huayihai manufactures custom copper paste filled via PCBs for OEM manufacturers based on Gerber files, engineering drawings, and technical specifications.

This PCB uses a 4-layer reference construction with IPC Class 3 copper paste hole plugging and ENIG surface finish to support automotive power applications that require reliable via quality, stable electrical connections, and consistent manufacturing quality. Layer count, board thickness, base material, copper thickness, and solder mask are manufactured to customer specifications rather than fixed to a single standard design.

Custom Manufacturing Only

We manufacture copper paste filled via PCBs according to customer Gerber files and technical specifications. We do not supply ready-made replacement circuit boards.
